気での使用中に遅れ割れが発生することがある。When the base material is carbon steel or low alloy steel, when SUS 304 bolts are stud welded, the dilution ratio of the components in the stud weld varies depending on the contact conditions, but is 40-60%, so the weld metal is 9%. Cr-4% Ni composition and martensitic structure, Vickers hardness of 400 Hv or more, low bending ductility, and delayed cracking may occur immediately after welding or during use in an atmosphere that absorbs hydrogen. .
これを防止するためには溶接金属部をオーステナイト単

ストがアツプする。There is also a method to use a stud of a material with a large amount of Cr and Ni, such as SUS 309 and SUS 310, to make it difficult for the martensite phase to form in the weld metal even when diluted, but the cost of the stud material increases. .
本発明は、従来のスタツドにみられる欠点のないスタツ
ド部材を提供しようとするものである。The present invention seeks to provide a stud member that does not have the drawbacks found in conventional studs.

である。The present invention relates to a stud welding member used when welding a carbon steel or low alloy steel member and an austenitic stainless steel stud by disposing a ferrule around the welded portion, and the tip of the stud is made of a high Ni alloy. Alternatively, it is a stud welding member characterized by being coated with a high Ni-Cr alloy thin plate.

下、水素に起因する低温割れ感受性の増大を防止する。By adjusting the amounts of Cr and Ni of alloys with a large amount of Cr and Ni from the stud arranged at the tip of the austenitic stainless steel stud, the weld metal of those alloys becomes a martensitic structure, so the stud body The decrease in bending ductility and the increase in cold cracking susceptibility due to hydrogen are prevented.

Table 3 shows the test results when 7Gr22, A387Gr11, EH36, and SUS 304 and SUS 309 having the same chemical composition shown in Table 1 were used as the stud material 1 under the welding conditions shown in Table 2.

は、曲げ試験の結果を第３表に示した。As the stud member of the present invention, a stud member having SUS 310 having the chemical composition shown in Table 1 and Inconel at the tip of the stud material 1 was used, and the results are also shown in Table 3. The material provided at the tip had a thickness of 0.5 mm and a height of 1.5 mm. Regarding the performance test of the welded portion, the results of the bending test are shown in Table 3.

接部を得ることができることが判る。From this, it is possible to use SUS 304, SUS 310, Inconel, and SUS 304 studs without using high-grade stud materials such as SUS 309 and SUS 310.
It can be seen that a good weld can be obtained by performing stud welding using a tip-disposed material such as Ni.

When it is more than 00Hv, it is judged as defective in the bending test. As in the case of the member of the present invention, the amounts of Cr and Ni in the weld metal reduced by the dilution of the base metal are supplemented by the tip-provided material to prevent the weld metal from becoming martensite, resulting in Vickers hardness 210 to 24.
At 0, a stud weld having good bending ductility can be obtained. Further, the softening significantly lowers the cold cracking susceptibility.
